Comparing the harvested power in two electromagnetic energy harvesting systems with linear and non-linear springs

Energy harvesting from wasted energy in the environment in order to run lowpower electronic devices is one of the common methods to use renewable energy. The main purpose of this technology is to provide sources of electrical energy in remote places and also to charge energy storage devices such as capacitors and batteries. The present study compares the harvested power from two electromagnetic energy harvesting systems with linear and non-linear spring (in two condition: COMSOL software and experimental results) which are vibrated by the human motion The innovation of this research is the spring that use in the energy harvesting system, which has linear spring on the one hand and is affected by non-linear spring on the other hand, as well as the validation of the simulation results using the design experimental system.
